I swapped out my Roush (came with car new) with a Steeda last weekend. Night and day. Also running a Steeda tune.

My CAI was missing two screws (not missing, two in there that were 8-32 instead of 10-32) so that cost me 44 mile round trip to Lowe's at 8pm. Otherwise, uneventful install.

I was confused though ... originally, Steeda supplied me with 91 and 93 octane tunes, and sent me a new tune when I bought the CAI through them for the 101mm MAF housing CAI ... and now they say the 91 and 93 are the same tune and uses factory fuel strategy to add timing for 93.

I'm not really sure what to make of the larger MAF housing. I asked Steeda if they flowed any better vs the older one and I was told that it was really more of an inventory change than anything else and there was not additional flow. But then why did they send you more tunes?

Any time you change the diameter of the maf housing you need an updated tune. It's a calculation thing, not an airflow thing.

Sure ... but the stock intake was sealed and only drew cold air from outside, too.

at the same time though, the stock airbox had a small area to pull air through, the surface area of the filters on the aftermarket CAIs is much larger, allowing them to still pull more air through, with much less restriction than the factory sealed box.

What really confused me with their tunes was a couple months ago, I received 91 and 93 octane tunes. A week ago, with the intake - they tell me they are the same tune, the 91 and 93. The tune seems to work fine ... no complaints ... I just do not understand why the 91 and 93 were different before (or so I was led to believe), and now they are not.

I get the cross section / velocity / calibration aspect and the tune requirement (I have one) just wondering why the CAI's supposedly make more power if they don't really flow "more" air.

I was asking in general ... not specifically in relation to the 101mm vs 95mm housings on the new and older Steeda intakes, respectively.

They really don't make any more power. Any gains are in the single digits and well within the margin of error of multiple dyno runs. However, since the size of the MAF housing changed, a tune is required and that is where the gains are. This makes it look like you gain 30-40 HP from the CAI, when in reality you are gaining 5-8 from the tune and 25-30 from the tune.

The Roush is a no-tune-required CAI ... I ran it with a Steeda 93 octane tune for a while. The car came with all sorts of Roush stuff ... including the intake ... sort of a dealer-made wanna-be-Roush package, so I never had the car without the intake. So, I can't compare.

I definitely feel more power with the Steeda intake and a new Steeda tune. Maybe it's placebo ... but so far I like it. The Roush doesn't have the sound that the Steeda does, either.

I haven't been terribly impressed. Not having had another brand, I can't say if they are all this way. The car did feel a "small" bit more peppy the first time I put it on.

What I don't like, is the whistling sound. I can't hear it for long, as my car is far louder than the whistle, but it is there. The newer filter they sent me, isn't so bad, but the original, which had some crushing on the mesh wire, was realllly bad.

I actually cleaned that filter, and then it wouldn't retain oil...at all. Literally would leak all oil 100% and turn a grayish white. I washed so much oil out of the inside of my engine compartment when I got the replacement filter and cleaned up to put it in. I might still have the pictures somewhere. It was bad.

Honestly, my mistake, I purchased the roush cai, then later an sct tuner from AM/BAMA. I wish I had purchased a tuner before hand, as I would have rather put a little more money into a better CAI than to have to replace it now.

yes BTW the car is tuned, but I ran the roush for a few months without it.

I have not heard anything about the BBK on the coyote, I will say that I just purchased my second Steeda CAI for my 11 GTyesterday, I loved the first one that much. Fit and finish on the Steeda is amazing

I'm clearly going to go with performance first, but I like the look of the chrome BBK. Unfortunately, that doesn't mean squat if it doesn't do much for the car.

I have the bbk strictly for the look and I also got a tune. I figured there's no real difference in any cold air intake so I mine as well get the one that I think looks the best. I have never had any issues and really like it.
